Within the framework of the circular economy,the waste litchi’s skins were upgraded and transformed into electrocatalysts for oxygen reduction reaction(ORR)and hydrogen evolution reaction(HER).The waste litchi’s skins were pyrolyzed,activated,and then used as carbon support for fabricating metal–nitrogen–carbons(m–N–Cs)which belong to a promising class of platinum group metal-free *** activated char was functionalized with transition metal(Fe,Ni,and Co)-phthalocyanine(Pc)in monometallic and bimetallic fashion by subjecting it to a thermal treatment at 600 and 900◦*** samples functionalized at 900℃ showed higher performance for HER due to the formation of metal nanoparticles,whereas the samples functionalized at 600℃ showed higher performance for ***,sample Ni–Co 900 had an overpotential of−0.38 V for HER,while the sample Fe 600 was the most active electrocatalyst for ORR by demonstrating the onset potential of∼0.9 V(a half-wave potential of∼0.81 V)with the least production of unwanted peroxide anion.

Fagonia cretica L. is an important component of mediterranean dry grasslands and a rare and isolated species of Italian flora. In this study, an assessment is presented on the distribution, habitat, and conservation status of F. cretica in Italy. The results of field investigation and herbarium analysis show that this species grows in a small area within the southern Calabria region characterized by a warmest and driest mediterranean climate on the Italian peninsula. F. cretica is a semi-desert plant species growing in Italy in only one peripheral and isolated population at the northern limit of its distribution. Plant community analysis, using the phytosociological method, shows that F. cretica grows in wintergreen perennial dry grasslands dominated by Lygeum {partum and Hyparrhenia hirta. F. crelica plant communities are located in thermo-xeric habits such as south-, southeast- and east-facing slopes on clays and sandy clays in southern Calabria. The population of F. cretica is fragmented in six neighbouring localities, with two of which belonging to a Site of Community Importance （SC1）. The conservation status of F. cretica population is not very good, and is defined as ＂Critically Endangered＂ in accordance with IUCN criteria. There are many threats affecting the F. crelica population in ltaly, primarily the changes in land uses due to urban expansion and reforestation with exotic plants. The southern end of the Italian peninsula hosts other plants from thermo-xeric habits that do not adapt to the current local climate. This territory can be considered as a microrefugia for plants currently distributed in the arid territory of the southern mediterranean. These results contribute to the discussion of some conservation measures, and the possibility of establishing a micro-reserve. For all these reasons, we propose to include F. cretica in the lists of protected plant species at regional （Calabria） and country （Italy） scales in Italy.

Background:To evaluate the effectiveness and safety of cabazitaxel in castration-resistant prostate cancer patients aged>80 years,we performed a retrospective study on a sample of patients from 11 Italian cancer *** and methods:Fifty-seven patients aged>80 years were treated with cabazitaxel after previous failure with docetaxel;39 completed a comprehensive geriatric assessment questionnaire(34 fit and 5 vulnerable)and 8 patients(14%)had an Eastern Cooperative Oncology Group performance status(PS)>2,while most had a PS of 0-1(86%).Cabazitaxel was administered at a dose of 25 mg/m^(2)in 30(52%)patients and 20 mg/m^(2)or adapted schedules in 27(48%)*** schedules were adopted mainly in patients>85 years(75%),with a PS>2(87.5%),and those classified as vulnerable(100%).Results:The duration of treatment was 4.8 months and was comparable in all subgroups;disease control rate was reported in 36 patients(63%);prostate-specific antigen response was recorded in 18 patients(31.5%).median overall survival was 13.1 months regardless of age(85 years),but overall survival was reduced in vulnerable(7.2 months)and PS>2 patients(6.8 months).The most frequently documented grade 3-4 toxicities were neutropenia(14%)and diarrhea(10.5%).Six patients(10.5%)dropped out due to severe ***:Octogenarian patients can be treated with cabazitaxel with reduced doses or alternative schedules that are associated with less toxicity and fewer treatment *** geriatric assessment could facilitate more appropriate patient selection.

The hair follicle is a biological oscillator that alternates growth,regression,and rest phases driven by the sequential activation of the proliferation differentiation programs of resident stem cell *** activation of hair follicle stem cell niches and subsequent entry into the growing phase is mainly regulated by Wnt/β-catenin signalling,while regression and resting phases are mainly regulated by Tgf-β/Bmp/Smad activity.A major question still unresolved is the nature of the molecular switch that dictates the coordinated transition between both signalling *** we have focused on the role of Endoglin(Eng),a key co-receptor for members of the Tgf-β/Bmp family of growth *** an Eng haploinsufficient mouse model,we report that Eng is required to maintain a correct follicle cycling pattern and for an adequate stimulation of hair follicle stem cell *** further report thatβ-catenin binds to the Eng promoter depending on Bmp ***,we show thatβ-catenin interacts with Smad4 in a Bmp/Eng-dependent context and both proteins act synergistically to activate Eng promoter *** observations point to the existence of a growth/rest switching mechanism in the hair follicle that is based on an Eng-dependent feedback cross-talk between Wnt/β-catenin and Bmp/Smad signals.
